Well, I've used a vtkCleanPolyData and a vtkStripper to cleanup the result of the
vtkPolyDataConnectivityFilter. The output is the contour of the main object, consisting of one or
more cells containing contiguous lines.
Hope this is what you needed. Otherwise, what about send me some image to test your code?
